In the present investigation, estuarine clam, M.meretrix was employed to study effect of cadmium chloride stress on biochemical components of different soft tissues. During summer, monsoon and winter clams were subjected to chronic exposure (96 hours) to predetermined sub lethal concentrations of cadmium chloride. During the experimental period water samples were analyzed for temperature, pH, salinity, dissolved oxygen and cadmium content. It was observed that rainfall, salinity, oxygen saturation and temperature of estuarine water has profound effect on seasonal changes in biochemical content of M.meretrix. During summer cadmium content in estuarine water was below detectable level, while in monsoon and winter it was 0.005 and 0.001ug/ml respectively. Clams from control group showed low glycogen content in gills and high in gonad and foot . Clams from chronic sub lethal concentration showed increase in glycogen content in gill in monsoon, while hepatopancreas showed significant increase during winter. Clams from control and chronic group showed higher protein content in gonad and foot for three different seasons. In chronic group, cadmium induced toxicity caused significant depletion in gonad and foot, while gill and hepatopancreas showed significant elevation. Chronic exposure of cadmium chloride depleted lipids in all soft tissues, but depletion was significant (p<0.001) in hepatopancreas and mantle. Hepatopancreas showed 30.85 and 28.55% decrease in monsoon and winter respectively. During summer, mantle showed (39.77%) considerable depletion than hepatopancreas. In the present study, it was found that, alterations in total glycogen, proteins and lipids from control group were attributed to highly labile estuarine water parameters and breeding season of clams, while, alterations in clams from chronic group are moreover attributed to cadmium chloride stress.
